Blocks up to 30m (100 ft) across were catapulted up to 3km (almost 2 miles). Turbulent avalanches of ash and blocks swept down Ngauruhoe’s sides at about 60km (35 miles) per hour.If any of these assumptions are violated, then the technique fails and any ‘dates’ are false. Eleven samples were collected from five recent lava flows during field work in January 1996—two each from the 11 February 1949, 4 June 1954, and 14 July 1954 flows and from the 19 February 1975 avalanche deposits, and three from the 30 June 1954 flow (Figure 6).

Back in the 1940s, the American chemist Willard Libby used this fact to determine the ages of organisms long dead.
Most carbon atoms have six protons and six neutrons in their nuclei and are called carbon 12. But a tiny percentage of carbon is made of carbon 14, or radiocarbon, which has six protons and eight neutrons and is not stable: half of any sample of it decays into other atoms after 5,700 years.
Argon gas, brought up from deep inside the earth within the molten rock, was already present in the lavas when they cooled.
We know the true ages of the rocks because they were observed to form less than 50 years ago.
If the method fails on rocks when we have an independent eye-witness account, then why should we trust it on other rocks where there are no independent historical cross-checks?
However, we do know Someone who was present when all the earth’s rocks formed—the Creator Himself.
Because argon is a gas, it should escape to the atmosphere due to the intense heat of the lavas. The samples were sent progressively in batches to Geochron Laboratories in Cambridge, Boston (USA), for whole-rock potassium-argon (K–Ar) dating—first a piece of one sample from each flow, then a piece of the second sample from each flow after the first set of results was received, and finally, a piece of the third sample from the 30 June 1954 flow.
Of course, no geologist was present to test this assumption by observing ancient lavas when they cooled, but we can study modern lava flows. To also test the consistency of results within samples, second pieces of two of the 30 June 1954 lava samples were also sent for analysis. No specific location or expected age information was supplied to the laboratory.
However, it is well-known that if a radiometric ‘date’ contradicts a fossil-derived (evolutionary) age, the date is discarded as erroneous.
See Lubenow, M., The pigs took it all, “One little bit doesn’t make a difference.” It’s a good job CMI didn’t think like that.
Mt Ngauruhoe is thought to have been active for at least 2,500 years, with more than 70 eruptive periods since 1839, when European settlers first recorded a steam eruption.
